Azalea plant named Cotton Candy

ABSTRACT

A new variety of hybrid azalea plant particularly suited for greenhouse forcing because of its vigorous and well branching growth habits, its prolific breaking, and its abundant production of ruffled and semi-double blossoms of delicate shell pink and creamy white coloration.

BACKGROUND OF THE INVENTION

This new variety of azalea plant was discovered by me in 1961 as aresult of breeding efforts carried on by me at Oregon State University,Corvallis, Oreg., with the objective of producing an improvedpot-forcing greenhouse azalea having better flowering and keepingqualities. This plant originated as a seedling of Albert and Elizabeth(unpatented) × Satin Robe (unpatented) and was selected by me forpropagation and test because of its vigorous and well branched, butcompact, growth habit and the very unusual delicate shell pink andcreamy white coloring of its flowers.

Asexual propagation of this new plant was carried on by me and under mydirection by means of cuttings at Corvallis, Oreg., and many successivegenerations of this plant have demonstrated that its distinctive andcommercially advantageous characteristics are firmly fixed and hold truefrom generation to generation.

DESCRIPTION OF THE DRAWINGS

My new variety of azalea is illustrated by the accompanying photographicdrawing in which the upper view shows a typical specimen of the pottedplant in full bloom and the lower view shows details of a typical budand the fully opened flower. The drawing views are prints which show theflower colors as nearly true as can be obtained by conventionalphotographic procedures and the true colors are shown by the handpainted swatches mounted below the lower view, the left hand swatchshowing the Camelia Rose color of the petal margins and reverse sidesand the right hand swatch showing the Neyron Rose color of the lowerbody portion of the petals.

My new variety of azalea plant is particularly distinguished by its veryfloriferous habit and the shell pink and cream white coloring of itsflowers. The semi-double blossoms are also unique in their puckeredsatiny texture and the abundance of their production. This new varietyis distinctive in its vigorous, well branching growth habit, its veryprolific breaking which makes it ideally suited for greenhouse forcing,and in the excellent lasting quality of the blooming plant.

I claim:
 1. A new and distinctive variety of azalea plant substantiallyas herein shown and described, characterized by its prolific productionof delicate pink and creamy white, ruffled and puckered, semi-doubleblossoms; and by its vigorous, well branched growth habit underpot-forcing procedures in greenhouse culture.
